[llvm] [AMDGPU][MC] fix unused template warning during build (PR #116313)

[Brox Chen via llvm-commits]

https://github.com/broxigarchen created https://github.com/llvm/llvm-project/pull/116313

This is a non-functional change. Passing the opName to VINTERP_Real_gfx11_gfx12 pseduo to suppress the warning.
